Background
1. Field
[0001] The disclosure relates to portable communication devices or electronic devices. More
particularly, the disclosure relates to a portable communication devices or electronic
devices with sealing members.
2. Description of Related Art
[0002] Developing electronic information communication technology integrates various functionalities
into a single electronic device or portable communication device. For example, smartphones
pack the functionalities of a sound player, imaging device, and scheduler, as well
as the communication functionality and, on top of that, may implement more various
functions by having applications installed thereon.
[0003] The user of a portable communication device or electronic device may search, screen,
and obtain more information by accessing a network, but rather than simply using the
own functionalities or information (e.g., applications) of the electronic device.
Direct access to the network (e.g., wired communication) may enable quick and stable
communication establishment but its usability may be limited to a fixed location or
space. In accessing a network, wireless communication is free from locational or spatial
limitations and its transmission speed or stability approaches that of direct access.
In the near future, wireless communication is expected to establish communication
more rapidly and stably than direct access.
[0004] As smartphones or other personal/portable communication devices spread, user demand
for portability and use convenience is on the rise. For example, a touchscreen display
may not only serve as an output device of visual information but also provide a virtual
keyboard that replaces a mechanical input device (e.g., a button input device). As
such, portable communication devices or electronic devices may be made compact while
delivering further enhanced applicability (e.g., a larger screen). Flexible displays,
e.g., foldable or rollable displays, will become commercially available and electronic
devices are expected to deliver better portability and use convenience.
[0005] If a display or electronic device is foldable or rollable, it would be easier to
carry while providing a larger screen. To protect its internal electronic components
or battery from external impacts, the outer structure (e.g., housing) of the electronic
device may be rigid. For an electronic device to roll in/fold and roll out/unfold,
its outer structures may be coupled together to be movable or rotatable about each
other.
[0006] While moving or rotating with each other, the rigid outer structures may rub against
each other, causing noise or damage. An approach to address such issue is to leave
a gap between the respective rubbing portions of the two outer structures. However,
the gap may allow a foreign body to come in. Such foreign body may damage or contaminate
the electronic components of the electronic device. For example, the unwanted material
may be stuck between mechanical or electronic parts which move with respect to each
other, deforming or cracking the parts.
[0007] The above information is presented as background information only to assist with
an understanding of the disclosure. No determination has been made, and no assertion
is made, as to whether any of the above might be applicable as prior art with regard
to the disclosure.

[0024] FIG. 1 is a view illustrating an unfolded state of a portable communication device
or electronic device 100 according to an embodiment of the disclosure.
[0025] FIG. 2 is a view illustrating a folded state of the electronic device 100 of FIG.
1, according to an embodiment of the disclosure.
[0026] In the following description, a pair of housing structures are rotatably coupled
together via a hinge structure, for example. However, it should be noted that the
portable communication device or electronic device according to various embodiments
of the disclosure is not limited thereto. For example, according to various embodiments,
the portable communication device or electronic device may include three or more housing
structures. As used herein, a "pair of housing structures" may mean two rotatably-coupled
housing structures among three or more housing structures.
[0027] Referring to FIG. 1, an electronic device 100 may include a pair of housing structures
110 and 120 coupled together via a hinge structure (e.g., the hinge structure 164a
of FIG. 3) to be rotatable to fold to each other, a hinge cover 165 covering foldable
portions of the pair of housing structures 110 and 120, and a display 130 (e.g., a
flexible display or foldable display) disposed or received in a space formed by the
pair of housing structures 110 and 120. The hinge cover 165 may be positioned between
at least a portion of the first housing structure 110 and at least a portion of the
second housing structure 120. The hinge structure 164a may be disposed between the
display 130 and the hinge cover 165 and be connected to the first housing structure
110 and the second housing structure 120. According to an embodiment, the electronic
device 100 may include a foldable housing rotatably coupled from the position in which
the pair of housing structures 110 and 120 are folded together to the position in
which the pair of housing structures 110 and 120 are unfolded flat. In the disclosure,
when the pair of housing structures 110 and 120 are unfolded side-by-side, the surface
where the display 130 is in may be defined as a 'front surface' of the electronic
device 100, and its opposite surface may be defined as a 'back surface' of the electronic
device 100. The surface surrounding the space between the front and back surfaces
may be defined as a 'side surface' of the electronic device 100.
[0028] According to an embodiment, the pair of housing structures 110 and 120 may include
a first housing structure 110, a second housing structure 120, a first back cover
140, and a second back cover 150. The pair of housing structures 110 and 120 of the
electronic device 100 are not limited to the shape and coupling shown in FIGS. 1 and
2 but may rather be implemented in other shapes or via a combination and/or coupling
of other components. For example, the first housing structure 110 and the first back
cover 140 may be integrally formed with each other, and the second housing structure
120 and the second back cover 150 may be integrally formed with each other. According
to an embodiment, the first housing structure 110 may include the first back cover
140, and the second housing structure 120 may include the second back cover 150.
[0029] According to an embodiment, the first housing structure 110 and the second housing
structure 120 may be positioned on opposite sides of a first axis, e.g., a folding
axis A, and they may be overall symmetrical in shape with each other with respect
to the folding axis A. According to an embodiment, the first housing structure 110
and the second housing structure 120 may be rotated on the hinge structure 164a or
hinge cover 165 with respect to different folding axes. For example, the first housing
structure 110 and the second housing structure 120 each may be rotatably coupled to
be rotatable on the hinge structure 164a or hinge cover 165. According to an embodiment,
as the first housing structure 110 and the second housing structure 120 each are rotated
around the folding axis A or different folding axes, they may rotate with respect
to each other from the position where two different areas of the front surface face
each other to the position where the two different areas of the front surface are
inclined or unfolded side-by-side.
[0030] As used herein, when A and B are positioned or extend side-by-side, it may mean that
A and B are positioned at least partially next to each other or at least partially
in parallel with each other. According to an embodiment, when A and B are disposed
(or arranged) side-by-side, it may mean that A and B are disposed (or arranged) to
face in the same direction or directions parallel with each other. According to an
embodiment, even when A and B are inclined with each other in an angle range from
about 160 degrees to about 180 degrees, A and B may be said to be disposed (or arranged)
side-by-side. In the following description, although the example phrases "side-by-side"
and "in parallel with each other" may be used to describe the corresponding structures,
the shape or arrangement of the structures may easily be appreciated from the accompanying
drawings.
[0031] According to an embodiment, the first housing structure 110 and the second housing
structure 120 may form different angles or distances depending on whether they are
in an unfolded state (or, extended state, flat state, or open state) or folded state
(or folding state), or in a state therebetween. According to an embodiment, the first
housing structure 110 and the second housing structure 120 may be symmetrical in shape
except that the first housing structure 110 further includes a sensor area 131d where
various sensors are arranged. Alternatively, the sensor area 131d may be disposed
in the second housing structure 120, not the first housing structure 110, or another
sensor area may be included in the second housing structure 120.
[0032] According to an embodiment, in the unfolded state of the electronic device 100, the
first housing structure 110 may be connected to the hinge structure (e.g., the hinge
structure 164a of FIG. 3) and may include a first surface 111 disposed to face the
front surface of the electronic device 100, a second surface 112 facing away from
the first surface 111, and a first side surface member 113 surrounding at least a
portion of the space between the first surface 111 and the second surface 112. According
to an embodiment, the first side surface member 113 may include a first side surface
113a disposed in parallel with the folding axis A, a second side surface 113b extending
from one end of the first side surface 113a in a direction perpendicular to the folding
axis A, and a third side surface 113c extending from the other end of the first side
surface 113a in a direction perpendicular to the folding axis A. As used herein, the
term "perpendicular" or "parallel" may be interchangeably used with "partially perpendicular"
or "partially parallel." In some embodiments, "parallel" or "perpendicular" may also
mean "inclined in an angle range within about 10 degrees."
[0033] According to an embodiment, the second housing structure 120 may be connected to
the hinge structure (e.g., the hinge structure 164a of FIG. 3) and, in the unfolded
state of the electronic device 100, the second housing structure 120 may include a
third surface 121 disposed to face the front surface of the electronic device 100,
a fourth surface 122 facing away from the third surface 121, and a second side surface
member 123 surrounding at least a portion of the space between the third surface 121
and the fourth surface 122. According to an embodiment, the second side surface member
123 may include a fourth side surface 123a disposed in parallel with the folding axis
A, a fifth side surface 123b extending from one end of the fourth side surface 123a
in a direction perpendicular to the folding axis A, and a sixth side surface 123c
extending from the other end of the fourth side surface 123a in a direction perpendicular
to the folding axis A. According to an embodiment, the third surface 121, in the folded
state, may be disposed to face the first surface 111. According to an embodiment,
the second side surface member 123 may be formed in substantially the same shape or
material as the first side surface member 113 although they may partially differ in
their specific shapes.
[0034] According to an embodiment, the electronic device 100 may include a recess 101 to
receive the display 130 via a structural shape combination of the first housing structure
110 and the second housing structure 120. The recess 101 may have substantially the
same size as the display 130. According to an embodiment, due to the sensor area 131d,
the recess 101 may have two or more different widths W1 and W2 in the direction perpendicular
to the folding axis A. For example, the recess 101 may have a first width W1 between
a first portion 120a, parallel with the folding axis A, of the second housing structure
120, and a first portion 110a, formed at an edge of the sensor area 131d, of the first
housing structure 110 and a second width W2 formed by a second portion 120b of the
second housing structure 120 and a second portion 110b, which is parallel with the
folding axis A and does not correspond to the sensor area 13 1d, of the first housing
structure 110. In this case, the second width W2 may be larger than the first width
W1. For example, the recess 101 may be formed with the first width W1 between the
first portion 110a of the first housing structure 110 and the first portion 120a of
the second housing structure 120, which are asymmetrical in shape with each other,
and the second width W1 between the second portion 110b of the first housing structure
110 and the second portion 120b of the second housing structure 120, which are symmetrical
in shape with each other. According to an embodiment, the first portion 110a and second
portion 110b of the first housing structure 110 may be formed to have different distances
from the folding axis A. The width of the recess 101 is not limited thereto. According
to an embodiment, the recess 101 may have two or more different widths depending on
the shape of the sensor area 131d or the asymmetrical shape portions of the first
housing structure 110 and the second housing structure 120.
[0035] According to an embodiment, the first housing structure 110 and the second housing
structure 120 may at least partially be formed of a metal or non-metallic material
with a rigidity selected to support the display 130. According to an embodiment, the
first housing structure 110 and the second housing structure 120 may at least partially
include an electrically conductive material. When the first housing structure 110
and the second housing structure 120 include an electrically conductive material,
the electronic device 100 may transmit/receive radio waves via the electrically conductive
portions of the first housing structure 110 and the second housing structure 120.
For example, the processor or communication module of the electronic device may perform
wireless communication using a portion of the first housing structure 110 and the
second housing structure 120.
[0036] According to an embodiment, the sensor area 131d may be formed adjacent to one corner
of the first housing structure 110 and to have a predetermined area. However, the
placement, shape, or size of the sensor area 131d is not limited to that shown in
the drawings. For example, according to an embodiment, the sensor area 131d may be
provided in a different corner of the first housing structure 110 or in any area between
the top corner and the bottom corner. According to an embodiment, the sensor area
131d may be disposed in at least an area of the second housing structure 120. According
to an embodiment, the sensor area 131d may be disposed to extend to the first housing
structure 110 and the second housing structure 120. According to an embodiment, the
electronic device 100 may include components exposed from its front surface through
the sensor area 131d or one or more openings prepared in the sensor area 131d and
may perform various functions by way of the components. The components arranged in
the sensor area 131d may include at least one of, e.g., a front camera device, a proximity
sensor, an illuminance sensor, an iris recognition sensor, an ultrasonic sensor, or
an indicator.
[0037] According to an embodiment, the first back cover 140 may be disposed on the second
surface 112 of the first housing structure 110 and may have a substantially rectangular
periphery. According to an embodiment, the periphery of the first back cover 140 may
be at least partially surrounded by the first housing structure 110. Similarly, the
second back cover 150 may be disposed on the fourth surface 122 of the second housing
structure 120 and its periphery may be at least partially surrounded by the second
housing structure 120.
[0038] In the shown embodiment, the first back cover 140 and the second back cover 150 may
be substantially symmetrical in shape with respect to the folding axis A. According
to an embodiment, the first back cover 140 and the second back cover 150 may have
other various different shapes. According to an embodiment, the first back cover 140
may be integrally formed with the first housing structure 110, and the second back
cover 150 may be integrally formed with the second housing structure 120.
[0039] According to an embodiment, a combined structure of the first back cover 140, the
second back cover 150, the first housing structure 110, and the second housing structure
120 may provide a space where various components (e.g., a printed circuit board, antenna
module, sensor module, or battery) of the electronic device 100 may be arranged. According
to an embodiment, one or more components may be arranged or visually exposed on/through
the back surface of the electronic device 100. For example, one or more components
or sensors may be visually exposed through a first back surface area 141 of the first
back cover 140. According to an embodiment, the sensor may include a proximity sensor,
a rear camera device, and/or flash. According to an embodiment, a sub display 152
may be at least visually exposed through a second back surface area 151 of the second
back cover 150.
[0040] The display 130 may be disposed in a space formed by the pair of housing structures
110 and 120. For example, the display 130 may be seated in a recess (e.g., the recess
101 of FIG. 1) formed by the pair of housing structures 110 and 120, and the display
130 may be disposed to occupy substantially most of the front surface of the electronic
device 100. For example, the front surface of the electronic device 100 may include
the display 130, a partial area (e.g., an edge area) of the first housing structure
110, which is adjacent to the display 130, and a partial area (e.g., an edge area)
of the second housing structure 120. According to an embodiment, the back surface
of the electronic device 100 may include the first back cover 140, a partial area
(e.g., an edge area) of the first housing structure 110, which is adjacent to the
first back cover 140, the second back cover 150, and a partial area (e.g., an edge
area) of the second housing structure 120, which is adjacent to the second back cover
150.
[0041] According to an embodiment, the display 130 may mean a display at least a portion
of which may be transformed to be flat or curved. According to an embodiment, the
display 130 may include a folding portion 131c, a first portion 131a disposed on one
side of the folding portion 131c (e.g., a right-hand area of the folding portion 131c),
and a second portion 131b disposed on the opposite side of the folding portion 131c
(e.g., a left-hand area of the folding portion 131c). For example, the first portion
131a may be disposed on the first surface 111 of the first housing structure 110,
and the second portion 131b may be disposed on the third surface 121 of the second
housing structure 120. For example, the display 130 may extend from the first surface
111 through the hinge cover 165 or the hinge structure 164a of FIG. 3 to the third
surface 121, and its portion (e.g., the folding portion 131c) corresponding to, at
least, the hinge cover 165 or hinge structure 164a may be a flexible portion that
may transform from flat to curved.
[0042] According to an embodiment, the segmentation of the display 130 is merely an example,
and the display 130 may be divided into a plurality of (e.g., four or more or two)
areas depending on the structure or function of the display 130. As an example, in
the embodiment shown in FIG. 1, the folding portion 131c may extend in the vertical
axis (e.g., the y axis of FIG. 3) parallel with the folding axis A, and the area of
the display 130 may be divided by the folding portion 131c or the folding axis A.
In another embodiment, the area of the display 130 may be divided by another folding
portion (e.g., a folding portion parallel with the horizontal axis (e.g., the x axis
of FIG. 3) or another folding axis (e.g., a folding axis parallel with the x axis
of FIG. 3). The above-described area segmentation means that it may be done so physically
by the pair of housing structures 110 and 120 and hinge structure (e.g., the hinge
cover 165 or the hinge structure 164a of FIG. 3) and, substantially, one display 130
may be disposed in the area or space provided by the pair of housing structures 110
and 120 and hinge structure (e.g., the hinge cover 165 or hinge structure 164a of
FIG. 3) to display a single whole screen.
[0043] According to an embodiment, the first portion 131a and the second portion 131b may
be overall symmetrical in shape with respect to the folding portion 131c. However,
unlike the second portion 131b, the first portion 131a may include a notch area (e.g.,
the notch area 133 of FIG. 3) that provides the sensor area 131d and, in the remaining
area, be symmetrical in shape with the second portion 131b. For example, the first
portion 131a and the second portion 131b may include symmetrical portions and asymmetrical
portions.
[0044] Referring to FIG. 3, the hinge cover 165 may be disposed between the first housing
structure 110 and the second housing structure 120 to hide the internal components
(e.g., the hinge structure 164a of FIG. 3). According to an embodiment, the hinge
cover 165 may be hidden by a portion of the first housing structure 110 and second
housing structure 120 or be exposed to the outside depending on the operation state
(e.g., the unfolded state or folded state) of the electronic device 100. For example,
the hinge cover 165 may be exposed more in the folded state than in the unfolded state.
[0045] Described below are the operation of the first housing structure 110 and the second
housing structure 120 and each area of the display 130 depending on the operation
state (e.g., the unfolded state and folded state) of the electronic device.
[0046] According to an embodiment, when the electronic device 100 is in the unfolded state
(e.g., the state as shown in FIG. 1), the first housing structure 110 and the second
housing structure 120 are 180-degree angled therebetween, and the first portion 131a
and second portion 131b of the display 130 may be placed to display screen in the
same direction, e.g., in directions parallel with each other. The folding portion
131c may be flush with the first portion 131a and the second portion 131b.
[0047] According to an embodiment, when the electronic device is in the folded state (e.g.,
the state as shown in FIG. 2), the first housing structure 110 and the second housing
structure 120 may face each other. For example, in the folded state (e.g., the state
as shown in FIG. 2) of the electronic device 100, the first portion 131a and the second
portion 131b of the display 130 may be rendered to face each other, angled at a small
angle (e.g., from 0 degrees to 10 degrees) therebetween. In the folded state (e.g.,
the state as shown in FIG. 2) of the electronic device 100, the folding portion 131c
may at least partially form a curved surface with a predetermined curvature.
[0048] According to an embodiment, when the electronic device 100 is in an intermediate
state, the first housing structure 110 and the second housing structure 120 may be
angled therebetween at a predetermined angle, e.g., 90 degrees or 120 degrees. For
example, in the intermediate state, the first portion 131a and second portion 131b
of the display 130 may be angled therebetween at an angle larger than the angle when
it is in the folded state and smaller than the angle when it is in the unfolded state.
The folding portion 131c may at least partially have a curved surface with a predetermined
curvature and, in this case, the curvature may be smaller than that when it is in
the folded state.
[0049] FIG. 3 is an exploded perspective view illustrating a portable communication device
or electronic device 100 according to an embodiment of the disclosure.
[0050] Referring to FIG. 3, according to an embodiment, an electronic device 100 may include
a display 130, a supporting member assembly 160, at least one printed circuit board
170, a first housing structure 110, a second housing structure 120, a first back cover
140, and a second back cover 150. In the disclosure, the display 130 may be interchangeably
used with a display module or display assembly.
[0051] The display 130 may include a display panel 131 (e.g., a flexible display panel)
and one or more plates 132 or layers seated on the display panel 131. According to
an embodiment, the plate 132 may be disposed between the display panel 131 and the
supporting member assembly 160. The display panel 131 may be disposed on at least
a portion of one surface (e.g., the Z-axis facing surface of FIG. 3) of the plate
132. The plate 132 may have a shape corresponding to the display panel 131. For example,
a portion of the plate 132 may have a shape corresponding to the shape of the notch
area 133 of the display panel 131.
[0052] The supporting member assembly 160 may include a first supporting member 161, a second
supporting member 162, a hinge structure 164a disposed with the first supporting member
161 and the second supporting member 162, a hinge cover 165 covering the hinge structure
164a when the hinge structure 164a is viewed from the outside, and a wiring member
(e.g., a flexible printed circuit board (FPCB)) crossing the first supporting member
161 and the second supporting member 162. According to an embodiment, the supporting
member assembly 160 may include a first hinge plate 164b mounted on the first supporting
member 161 and a second hinge plate 164c mounted on the second supporting member 162.
According to an embodiment, the wiring member may be disposed in a direction (e.g.,
the x-axis direction) crossing the first supporting member 161 and the second supporting
member 162 and may be hidden by the first hinge plate 164b or second hinge plate 164c
and they are not shown in FIG. 3.
[0053] According to an embodiment, the first hinge plate 164b may be mounted inside the
first housing structure 110, and the second hinge plate 164c may be mounted inside
the second housing structure 120. According to an embodiment, the first hinge plate
164b may be directly mounted on the first supporting member 161, and the second hinge
plate 164c may be directly mounted on the second supporting member 162. According
to an embodiment, the first hinge plate 164b (or second hinge plate 164c) may be directly
mounted in another structure (e.g., a first rotation supporting surface 114 or second
rotation supporting surface 124) inside the first housing structure 110 (or the second
housing structure 120). For example, the structure in which the first hinge plate
164b (or the second hinge plate 164c) is mounted inside the first housing structure
110 (or the second housing structure 120) may be varied according to embodiments.
In another embodiment, the hinge structure 164a may be mounted on the first hinge
plate 164b and the second hinge plate 164c, rotatably connecting the second hinge
plate 164c to the first hinge plate 164b. For example, a folding axis (e.g., the folding
axis A of FIG. 1) may be formed by the hinge structure 164a, and the first housing
structure 110 and the second housing structure 120 (or the first supporting member
161 and the second supporting member 162) may be rotated on each other substantially
with respect to the folding axis A.
[0054] According to an embodiment, the supporting member assembly 160 may be disposed with
the plate 132 and at least one printed circuit board 170. As an example, the first
supporting member 161 may be disposed with the first portion 131a of the display 130
and a first printed circuit board 171. The second supporting member 162 may be disposed
with the second portion 131b of the display 130 and a second printed circuit board
172.
[0055] As mentioned above, the at least one printed circuit board 170 may include the first
printed circuit board 171 disposed on the first supporting member 161 and the second
printed circuit board 172 disposed on the second supporting member 162. The first
printed circuit board 171 and the second printed circuit board 172 may be disposed
inside a space formed by the second antenna module, the first housing structure 110,
the second housing structure 120, the first back cover 140, and the second back cover
150. Components for implementing various functions of the electronic device 100 may
be mounted on the first printed circuit board 171 and the second printed circuit board
172.
[0056] According to an embodiment, the first housing structure 110 and the second housing
structure 120 may be assembled together to be coupled to both sides of the supporting
member assembly 160, with the display 130 coupled to the supporting member assembly
160. The first housing structure 110 and the second housing structure 120 may be slidably
coupled to two opposite sides of the supporting member assembly 160, e.g., the first
supporting member 161 and the second supporting member 162, respectively. The first
supporting member 161 and the second supporting member 162 may substantially be received
in the first housing structure 110 and the second housing structure 120 and, according
to an embodiment, may be interpreted as the respective portions of the first housing
structure 110 and the second housing structure 120.
[0057] According to an embodiment, the first housing structure 110 may include a first rotation
supporting surface 114, and the second housing structure 120 may include a second
rotation supporting surface 124 corresponding to the first rotation supporting surface
114. The first rotation supporting surface 114 and the second rotation supporting
surface 124 may include a curved surface corresponding to a curved surface included
in the hinge cover 165.
[0058] According to an embodiment, when the electronic device 100 is in the unfolded state
(e.g., the state as shown in FIG. 1), the first rotation supporting surface 114 and
the second rotation supporting surface 124 may cover the hinge cover 165, allowing
the hinge cover 165 to be not or minimally exposed to the back surface of the electronic
device 100. According to an embodiment, when the electronic device 100 is the folded
state (e.g., the state as shown in FIG. 2), the first rotation supporting surface
114 and the second rotation supporting surface 124 may rotate along the curved surface
of the hinge cover 165, maximally exposing the hinge cover 165 to the back surface
of the electronic device 100.
[0059] In the above description, the ordinal numbers as in the first housing structure 110,
second housing structure 120, first side surface member 113 and the second side surface
member 123 have been used merely for distinguishing the components, and it should
be noted that the scope of the disclosure is not limited by the use of ordinal numbers.
For example, although the sensor area 131d is formed in the first housing structure
110 in the above example, the sensor area 131d may be formed in the second housing
structure 120 or in each of the first housing structure 110 and the second housing
structure 120. According to an embodiment, although the first back surface area 141
and the sub display 152 are disposed in the first back cover 140 and the second back
cover 150, respectively, the first back surface area 141 for placing, e.g., a sensor,
and the sub display 152 for outputting the screen, both, may be disposed in either
the first back cover 140 or the second back cover 150.
[0060] The following description is made with reference to FIGS. 1 to 3 as necessary. In
the following embodiments, the components identical to those in the above embodiments
or easy to understand from the description of the above embodiments are denoted with
or without the same reference numerals and their detailed description may be skipped.
In the following description, the state (e.g., the state as shown in FIG. 2) in which
the first housing structure 110 and the second housing structure 120 are folded to
face each other may be denoted a "first position," and the state (e.g., the state
as shown in FIG. 1) in which the first housing structure 110 and the second housing
structure 120 are unfolded side-by-side may be denoted a "second position."
[0061] According to an embodiment, the electronic device 100 may include sealing members
181 and 182 provided between the hinge cover 165 and the first housing structure 110
and/or between the hinge cover 165 and the second housing structure 120. According
to an embodiment, the electronic device 100 may include other sealing members 183
provided between the hinge cover 165 and the display 130. The sealing structure formed
between the hinge cover 165 and the first housing structure 110 (or second housing
structure 120) is described below with reference to FIGS. 4 to 6. As used herein,
'sealing structure' may mean a structure for blocking off influx of foreign bodies,
whether solid or liquid, such as dust or chips. Members or components (e.g., the sealing
members 181, 182, and 183 of FIG. 4 described below) forming the 'sealing structure'
may be formed of an elastic material that may accumulate elastic force when compressed
by external force and, when the external force is released, may go back to its original
shape. For example, the components or members forming the 'sealing structure' may
prevent influx of, at least, a solid or liquid foreign body into the inside of the
electronic device 100.
[0062] FIG. 4 is an exploded perspective view illustrating a configuration in which a first
sealing member (e.g., the first sealing member 181 of FIG. 3) or a second sealing
member (e.g., the second sealing member 182 of FIG. 3) is mounted in a portable communication
device or electronic device (e.g., the electronic device 100 of FIGS. 1 to 3) according
to an embodiment of the disclosure.
[0063] FIG. 5 is a cross-sectional view illustrating a folded position of a portable communication
device or electronic device (e.g., the electronic device 100 of FIGS. 1 to 3) according
to an embodiment of the disclosure.
[0064] FIG. 6 is a cross-sectional view illustrating an unfolded position of a portable
communication device or electronic device (e.g., the electronic device 100 of FIGS.
1 to 3) according to an embodiment of the disclosure.
[0065] Referring to FIGS. 4 to 6, the first sealing member 181 may include an elastic material,
such as rubber, silicone, sponge, polycarbonate, or Teflon
™, and the first sealing member 181 may extend in the lengthwise direction (e.g., the
y direction of FIG. 3) of the electronic device 100. According to an embodiment, the
first sealing member 181 may be provided between a first housing structure (e.g.,
the first housing structure 110 of FIG. 3) and a hinge cover (e.g., the hinge cover
165 of FIG. 3), forming a sealing structure between the first housing structure 110
and the hinge cover 165.
[0066] According to an embodiment, a first rotation supporting surface (e.g., the first
rotation supporting surface 114 of FIG. 3) or a second rotation supporting surface
(e.g., the second rotation supporting surface 124 of FIG. 3) may include a curved
surface 265a or 265b corresponding to the outer circumferential surface of the hinge
cover 165. For example, the first rotation supporting surface 114 may be disposed
to at least partially surround the outer circumferential surface of the hinge cover
165. When the first housing structure 110 or the second housing structure 120 rotates
between the first position and the second position, the first rotation supporting
surface 114 may substantially move while at least partially facing the outer circumferential
surface of the hinge cover 165, partially hiding or exposing the hinge cover 165.
According to an embodiment, the hinge cover 165 may be externally exposed more in
the first position than in the second position. When two structures (e.g., the first
housing structure 110 and the hinge cover 165) with rigidity directly rub each other
in such a relative movement, noise or wear may occur as mentioned above. According
to an embodiment, a predetermined gap may be formed between the first rotation supporting
surface 114 and the outer circumferential surface of the hinge cover 165, preventing
noise or wear due to friction between the rigid structures.
[0067] According to an embodiment, the first sealing member 181 may seal off the gap between
the first housing structure 110 (e.g., the first rotation supporting surface 114)
and the hinge cover 165. For example, the internal space formed by a combination of
the first housing structure 110 and the hinge cover 165 may be connected to the external
space via the gap between the first housing structure 110 and the hinge cover 165,
and the first sealing member 181 may seal off the gap. According to an embodiment,
as including the elastic material, the first sealing member 181 may seal off the gap
between the first housing structure 110 and the hinge cover 165 while mitigating friction
in the rotation of the housing structures 110 and 120 and suppressing noise or wear
due to friction.
[0068] According to an embodiment, the first sealing member 181 may be mounted or attached
to the first rotation supporting surface 114. For example, the first sealing member
181 may be mounted in the first housing structure 110 and be positioned to contact
the hinge cover 165. Referring to FIG. 6, the first sealing member 181 may include
a fixing portion 181a and a sealing portion 181b. The fixing portion 181a may be mounted
in the first housing structure 110 (or the second housing structure 120) and extend
in the y direction of FIG. 3, with a predetermined width. According to an embodiment,
the sealing portion 181b may extend from the fixing portion 181a and tightly contact
the hinge cover 165. Although the first sealing member 181 is mounted or attached
to the first rotation supporting surface 114 in the instant embodiment, the disclosure
is not limited thereto. For example, the first sealing member 181 may be mounted on
the hinge cover 165 in the position or area where it remains hidden by the first housing
structure 110. For example, when the first sealing member 181 is mounted on the hinge
cover 165, the first sealing member 181 may be positioned to contact the first housing
structure 110.
[0069] According to an embodiment, in tight contact with the hinge cover 165, the sealing
portion 181b may at least partially be deformed to be inclinedly or curved with respect
to the fixing portion 181a. For example, the first sealing member 181 may include
a recessed portion 181c at least partially surrounded by the fixing portion 181a and
the sealing portion 181b. According to an embodiment, the sealing portion 181b may
be formed at least partially in an inclined or curved shape with respect to the fixing
portion 181a before coming in tight contact with the hinge cover 165. For example,
the first sealing member 181 may be made in a shape including the recessed portion
181c.
[0070] According to an embodiment, the second sealing member 182 may be mounted in the second
housing structure 120 and, although differing in shape or size, the second sealing
member 182 may readily be appreciated from the configuration of the first sealing
member 181. Thus, no detailed description of the second sealing member 182 is given
below.
[0071] FIG. 5 is a cross-sectional view of the electronic device 100, taken along line C-C
of FIG. 2, with the first housing structure 110 and the second housing structure 120
folded to face each other, for example. Referring to FIG. 5, in the first position,
the first sealing member 181 may be positioned adjacent to an edge of the hinge cover
165, and the second sealing member 182 may be positioned adjacent to the opposite
edge of the hinge cover 165. FIG. 6 is a cross-sectional view of the electronic device
100, taken along line B-B of FIG. 1, with the first housing structure 110 and the
second housing structure 120 unfolded side-by-side, for example. Referring to FIG.
6, in the second position, the first sealing member 181 and the second sealing member
182 may be positioned adjacent to each other.
[0072] According to an embodiment, although FIG. 6 illustrates that the sealing portion
181b overlaps the hinge cover 165, this is simply for the purpose of clearer illustration
of the shape of the first sealing member 181 or second sealing member 182. For example,
in the actual electronic device, the sealing portion 181b may be deformed while tightly
contacting the hinge cover 165. According to an embodiment, the sealing portion 181b
may deform and accrue elastic force, keeping it in tight contact with the hinge cover
165 in a stable manner. According to an embodiment, if the sealing portion 181b accumulates
excessive elastic force, an unnecessary load may be applied to the mechanical structure
(e.g., the first housing structure 110, second housing structure 120, or hinge cover
165). According to an embodiment, the recessed portion 181c may smooth deformation
of the sealing portion 181b, mitigating or preventing excessive accumulation of elastic
force or unnecessary overload to the mechanical structure.
[0073] According to an embodiment, in the unfolding or folding operation of the electronic
device 100, the first sealing member 181 or the second sealing member 182 may slide
and contact the outer circumferential surface of the hinge cover 165, allowing the
first sealing member 181 and the second sealing member 182 to remain in a stable sealing
structure. For example, the first sealing member 181 or the second sealing member
182 may seal off the gap between the first housing structure 110 and the hinge structure
164a or between the second housing structure 120 and the hinge structure 164a. Thus,
the internal space formed by a combination of the first housing structure 110, the
second housing structure 120, and the hinge cover 165 may be sealed off from the external
space by the first sealing member 181 or the second sealing member 182.
[0074] According to an embodiment, in configuring an electronic device (e.g., the electronic
device 100 of FIGS. 1 to 3) which is foldable or rollable, a plurality of rigid structures
(e.g., the first housing structure 110, the second housing structure 120, and/or the
hinge cover 165) may be combined to at least partially define an internal space. As
the plurality of rigid structures relatively move or rotate with respect to each other,
the electronic device 100 may be folded (or rolled up) or unfolded. A predetermined
gap secured where the plurality of rigid structures are coupled may prevent friction
that may occur in the relative movement or rotation. In various embodiments of the
disclosure, a sealing member (e.g., the first sealing member 181 or second sealing
member 182) may be placed at a gap left for preventing friction (e.g., the gap between
the plurality of rigid structures), preventing influx of an external foreign body
into the internal space. The sealing member includes an elastic material, suppressing
or mitigating noise or wear due to friction.
[0075] FIGS. 7 and 8 are cross-sectional views illustrating a configuration in which a modified
first sealing member (e.g., the first sealing member 181 of FIG. 3 or 5) or a modified
second sealing member (e.g., the second sealing member 182 of FIG. 3 or 5) is mounted
in a portable communication device or electronic device (e.g., the electronic device
100 of FIG. 1) according to various embodiments of the disclosure.
[0076] Referring to FIG. 7, a first sealing member 281 or second sealing member 282 may
include a body 281a or 282a formed of sponge. For example, the body 281a or 282a may
form a sealing structure between the first housing structure 110 (or the second housing
structure 120) and the hinge cover 165. Sponge is a kind of low-density elastic material,
providing a sealing structure between the first housing structure 110 and the hinge
cover 165 while reducing a load applied to the first housing structure 110 or hinge
cover 165 or friction in the folding/unfolding operation of the electronic device
200. According to an embodiment, if the body 281a or 282a which is a low-density elastic
material is damaged by an external factor, foreign bodies may occur. According to
an embodiment, the first sealing member 281 or the second sealing member 282 may include
a sheath layer 281b or 282b surrounding the body 281a or 282a. The sheath layer 281b
or 282b may be formed of a fabric material, preventing damage to the body 281a or
282a. According to an embodiment, various frictional coefficients may be set depending
on the material of the sheath layer 281b or 282b. For example, the sheath layer 281b
or 282b may reduce frictional force between the first sealing member 281 or second
sealing member 282 and the hinge cover 165.
[0077] Referring to FIG. 8, the hinge cover 165 may further include protrusions 383 at its
two opposite edges. The first sealing member 381 and the second sealing member 382
may tightly contact, in their entire width (e.g., the length measured along the x
direction of FIG. 3), the hinge cover 165, forming a sealing structure. According
to an embodiment, in the first position, e.g., with the electronic device 300 (e.g.,
the electronic device 100 of FIGS. 1 to 3) folded, the first sealing member 381 or
the second sealing member 382 may be positioned partially not in contact with the
hinge cover 165. The protrusion(s) 383, in the first position, may interfere with
the first sealing member 381 or second sealing member 382, compressing the first sealing
member 381 or second sealing member 382. For example, in the first position, the contact
area between the first sealing member 381 or second sealing member 382 and the hinge
cover 165 may slightly reduce, but more tight contact with the protrusion(s) 383 may
be obtained, thus keeping the sealing structure more stable. According to an embodiment,
the first sealing member 381 or second sealing member 382 may be formed of a lubricative
material, e.g., an acetal resin or Teflon
™ sheet, suppressing nose or wear to the hinge cover 165 despite friction with the
hinge cover 165.
[0078] According to an embodiment, the protrusion 383 may be an extending or projecting
portion of the hinge cover 165. For example, the protrusion 383 may have a rigid structure
like the hinge cover 165. Alternatively, the protrusion 383 may be formed of a different
material, e.g., an elastic material, than the rigid structure of the hinge cover 165.
When the protrusion 383 is formed of an elastic material, the protrusion 383 may be
formed by insert-molding while simultaneously coupled to the hinge cover 165.
[0079] According to an embodiment, as the display (e.g., the display 130 of FIG. 3) is coupled
with the rigid structures (e.g., the first housing structure 110, second housing structure
120, and hinge cover 165 of FIG. 3), an internal space of the electronic device (e.g.,
the electronic device 100 of FIGS. 1 to 3) may be defined. For example, the internal
space of the electronic device 100 may substantially mean a space surrounded by the
display 130 and the rigid structures.
[0080] The folding portion (e.g., the folding portion 131c of FIG. 3) of the display 130
may be deformed to be curved as the electronic device 100 folds or unfolds and, when
an external force is applied, it may be easily damaged. For example, coupling or attaching
the folding portion 131c of the display 130 to the rigid structure (e.g., the hinge
cover 165) may be limited. According to an embodiment, a gap may be formed between
the folding portion 131c and its corresponding rigid structure at the edge of the
display 130, providing a space to allow the folding portion 131c to be deformed to
be curved. According to an embodiment, the gap formed between the folding portion
131c and its corresponding rigid structure may serve as a path along which foreign
bodies may come in. According to an embodiment, the electronic device 100 may include
a third sealing member (e.g., the sealing member 183 of FIG. 3 or a third sealing
member 481a or 481b of FIG. 9 described below), forming a sealing structure between
the folding portion 131c and its corresponding rigid structure (e.g., the hinge cover
165). A sealing structure using the third sealing member is described below with reference
to FIGS. 9 to 12.
[0081] FIG. 9 is an exploded perspective view illustrating a configuration in which a third
sealing member 481a or 481b (e.g., the sealing member 181 of FIG. 3) is mounted in
a portable communication device or electronic device (e.g., the electronic device
100 of FIGS. 1 to 3) according to an embodiment of the disclosure.
[0082] Referring to FIG. 9, the electronic device 100 may include at least one third sealing
member 481a and 481b provided between the display (e.g., the display 130 of FIG. 3)
and the hinge cover (e.g., the hinge cover 165 of FIG. 3). According to an embodiment,
a pair of third sealing members 481a and 481b may be provided to contact or attach
to the top and bottom, respectively, of the hinge cover 165. According to an embodiment,
the third sealing members 481a and 481b may be disposed so that their bottom or side
contacts the hinge cover 165. According to an embodiment, the third sealing members
481a and 481b may substantially have their bottom or side attached to the hinge cover
165. When the display 130 is disposed on the hinge cover 165, the third sealing members
481a and 481b may contact the inner surface (e.g., the folding portion 131c of FIG.
2) of the display 130. For example, the third sealing members 481a and 481b may contact
two opposite ends of the folding portion 131c at the edge of the display 130, forming
a sealing structure between the folding portion 131c and the rigid structure (e.g.,
the hinge cover 165). According to an embodiment, the third sealing members 481a and
481b may be formed of a low-density elastic material, e.g., sponge. As the third sealing
members 481a and 481b are formed of a low-density elastic material, the load applied
to the display 130 by elastic force accrued by the third sealing members 481a and
481b may be small despite tight contact with the folding portion 131c in the folding/unfolding
operation of the electronic device 100.
[0083] FIG. 10 is a view illustrating a sealing structure formed on a display 130 in a portable
communication device or electronic device (e.g., the electronic device 100 of FIG.
3) according to an embodiment of the disclosure.
[0084] Referring to FIG. 10, the first portion 131a and second portion 131b of the display
130 may be mounted in the first housing structure 110 and second housing structure
120, remaining flat even in the folding/unfolding operation of the electronic device
100. For example, the first portion 131a and the second portion 131b may be mounted
in the rigid structures. According to an embodiment, the display 130 may include a
first attaching area 491a provided along the edge of the first portion 131a and a
second attaching area 491b provided along the edge of the second portion 131b. The
first attaching area 491a or second attaching area 491b may be mounted on a side surface
member (e.g., the first side surface member 113 of FIG. 1 or 2) of a rigid structure,
e.g., the first housing structure 110 or a side surface member (e.g., the second side
surface member 123 of FIG. 1 or 2) of the second housing structure 120. For example,
a sealing structure may be formed between the first portion 131a and the rigid structure
(e.g., the first housing structure 110 of FIGS. 1 to 3), corresponding to the first
attaching area 491a, and a sealing structure may be formed between the second portion
131b and the rigid structure (e.g., the second housing structure 120 of FIGS. 1 to
3), corresponding to the second attaching area 491b.
[0085] According to an embodiment, the display 130 may include contacting areas 493a and
493b at two opposite ends of the folding portion 131c, in the inner surface thereof.
According to an embodiment, the contacting areas 493a and 493b may be positioned at
the edge of the display 130 and abut the first attaching area 491a or second attaching
area 491b. For example, one of the contacting areas 493a and 493b (e.g., the contacting
area denoted with reference number 493a) may mean an area between one end of the first
attaching area 491a and an end of the second attaching area 491b, and the other of
the contacting areas 493a and 493b (e.g., the contacting area denoted with reference
number 493b) may mean an area between the other end of the first attaching area 491a
and the other end of the second attaching area 491b. According to an embodiment, the
first attaching area 491a, the second attaching area 491b, and the contacting areas
493a and 493b may be combined to form a closed loop or closed curve.
[0086] According to an embodiment, when the first attaching area 491a is attached to the
first housing structure 110, and the second attaching area 491b is attached to the
second housing structure 120, the contacting areas 493a and 493b may be positioned
corresponding to two opposite ends of the hinge cover 165. According to an embodiment,
the third sealing members 481a and 481b may contact one of the contacting areas 493a
and 493b, forming a sealing structure between an end of the folding portion 131c and
an end of the hinge cover 165.
[0087] FIG. 11 is a cross-sectional view illustrating a sealing structure formed by the
third sealing members 481a and 481b in a portable communication device or electronic
device (e.g., the electronic device 100 of FIGS. 1 to 3) according to an embodiment.
[0088] FIG. 12 is a cross-sectional view illustrating a sealing structure formed by the
third sealing member 481a, with a portable communication device or electronic device
(e.g., the electronic device 100 of FIGS. 1 to 3) folded, according to an embodiment
of the disclosure.
[0089] Referring to FIG. 11 is a cross-sectional view of the electronic device 100, taken
along, e.g., the folding axis A of FIG. 1. Referring to FIG. 11, in the second position,
the third sealing member 481a may tightly contact the display 130 (e.g., one of the
contacting areas 493a and 493b) while remaining substantially in a polygonal shape,
e.g., a cuboid. According to an embodiment, a coupling part(s) 464d may be provided
in the internal space of the hinge cover 165. The coupling part 464d may be provided
at, e.g., a hinge plate (e.g., the first hinge plate 164b or second hinge plate 164c
of FIG. 3), and the hinge structure 164a of FIG. 3 may be coupled to the first hinge
plate 164b or second hinge plate 164c via the coupling part 464d.
[0090] FIG. 12 is a cross-sectional view of a portion of the electronic device 100, taken
along line D-D of FIG. 11, illustrating a folded state of the first housing structure
110 and the second housing structure 120 in the first position, e.g., as shown in
FIG. 2 according to an embodiment of the disclosure. Referring to FIG. 12, in the
first position, the display 130, e.g., the folding portion 131c, may be at least partially
folded or curved, compressing the third sealing member 481a. For example, when the
display 130 is in the flat shape, the third sealing member 481a may be in the state
of being maximally extended in the electronic device 100 and, when a portion (e.g.,
the folding portion 131c or the contacting areas 493a and 493b) of the display 130
is curved, the third sealing member 481a may be compressed. The third sealing member
481a may be formed of a low-density elastic material, e.g., sponge and, although compressed,
the load applied to the display 130 may thus be tiny.
[0091] As set forth above, according to an embodiment, as the rigid structures (e.g., the
first housing structure 110, second housing structure 120, and hinge cover 165 of
FIGS. 1 to 3) are moved to each other or rotatably coupled together, the first sealing
member or second sealing member (e.g., the first sealing member 181 or second sealing
member 182 of FIG. 3) may form a stable sealing structure between the rigid structures.
For example, the electronic device 100 (e.g., the electronic device 100 of FIGS. 1
to 3) may be folded or rolled up in structure while preventing influx of foreign bodies
into the inside via the gap between the rigid structures.
[0092] According to an embodiment, for the portion that remains flat upon mounting the display
(e.g., the display 130 of FIG. 3 or 10), the edges (e.g., the first attaching area
491a and the second attaching area 491b) of the display may directly be attached to
the rigid structures (e.g., the first housing structure 110 and second housing structure
120 of FIGS. 1 to 3). According to an embodiment, in the portions (e.g., the contacting
areas 493a and 493b of FIG. 10) of the display, which are supposed to be curved, the
third sealing members (e.g., the third sealing members 481a and 481b of FIG. 9 or
11) may form a sealing structure. For example, the overall edge of the display 130
may be directly attached to the rigid structures to thereby form a sealing structure
but, in the portions of the display 130, which are to be curved, the third sealing
members 481a and 481b may form a sealing structure. According to an embodiment, the
areas (e.g., the first attaching area 491a and second attaching area 491b of FIG.
10) attached to the rigid structures in the edge of the display 130 and the areas
(e.g., the contacting areas 493a and 493b of FIG. 10), which contact the third sealing
members 481a and 481b, may be combined to form a closed curve. For example, the path
along which foreign bodies may enter between the display 130 and the rigid structure
may be blocked off.
[0093] FIG. 13 is a plan view illustrating a hinge cover (e.g., the hinge cover 165 of FIGS.
1 to 3) in a portable communication device or electronic device (e.g., the electronic
device 100 of FIGS. 1 to 3) according to an embodiment of the disclosure.
[0094] Referring to FIG. 13, the electronic device 100 may further include a first sticky
layer 581 provided in the internal space of the electronic device 100. The first sticky
layer 581 may include a gluing agent and allow foreign bodies present or moving inside
or around the electronic device 100 to stick thereto. For example, the first sticky
layer 581 may prevent free movement of, or contamination of the internal components
by foreign bodies inside the electronic device 100. According to an embodiment, the
first sticky layer 581 may be formed on an inner surface of the hinge cover (e.g.,
the hinge cover 165 of FIGS. 1 to 3). For example, a gluing agent may be directly
applied to the inner space of the hinge cover 165, or a gluing agent-applied film-type
base material may be attached, in an adequate position, to the inside of the electronic
device 100, thereby forming the first sticky layer 581.
[0095] According to an embodiment, the structures, e.g., the first housing structure 110,
second housing structure 120, hinge structure 164a, first hinge plate 164b, and second
hinge plate 164c, may frequently move or rotate with respect to each other, around
the hinge cover 165. Placing the above-described first sealing member 181, second
sealing member 182, and third sealing members 481a and 481b may largely block influx
of foreign bodies, but there is a chance of foreign bodies coming in due to relative
movement of the structures. According to an embodiment, the first sticky layer 581
may be provided on the inner surface of the hinge cover 165 and foreign bodies coming
in from around the hinge cover 165, if any, may stick to the first sticky layer 581.
For example, the first sticky layer 581 may be provided to stop foreign bodies from
moving, thereby preventing contamination or damage to the mechanical or electronic
components inside the electronic device 100.
[0096] FIGS. 14, 15, 16, 17, 18, and 19 are cross-sectional views illustrating a modified
first sealing member or second sealing member in a portable communication device or
electronic device according to various embodiments of the disclosure.
[0097] Referring to FIGS. 14 and 15, a first sealing member 681 may be disposed on a curved
surface 265a of the first housing structure 110, and a second sealing member 682 may
be disposed on a curved surface 265b of the second housing structure 120. According
to an embodiment, the first sealing member 681 and the second sealing member 682 may
be shaped to partially stick out, and they may at least partially contact the outer
circumferential surface of the hinge cover 165. According to an embodiment, in contact
with the outer circumferential surface of the hinge cover 165, the first sealing member
681 and the second sealing member 682 may be compressed and accumulate elastic force.
For example, the first sealing member 681 and the second sealing member 682 may seal
off the gap formed between the outer circumferential surface of the hinge cover 165
and each curved surface 265a and 265b, stopping foreign bodies (e.g., dust, chips,
or other solid particles) from entering the electronic device 100 (e.g., the electronic
device 100 of FIGS. 1 to 3) from the outside. While the electronic device 100 folds
or unfolds, the first sealing member 681 and the second sealing member 682 may slide
and contact the outer circumferential surface of the hinge cover 165 and they may
include a low friction-factor material, e.g., fabric or lubricative high-polymer material,
preventing noise or wear.
[0098] According to an embodiment, the hinge structure (e.g., the hinge structure 164a of
FIG. 3), from a structure perspective, may be a combination of a plurality of gears,
and the hinge structure may couple the first hinge plate 164b and the second hinge
plate 164c to be rotatable with respect to each other. According to an embodiment,
the hinge structure 164a may be coupled with the first hinge plate 164b or second
hinge plate 164c via the coupling part 464d of FIG. 11. In the cross-sectional view
of FIG. 14, when the hinge structure 164a includes an even number of gears, the first
housing structure 110 and the second housing structure 120 may be rotated reversely
with respect to each other. For example, in FIG. 14, when the first housing structure
110 rotates clockwise on the hinge structure 164a, the second housing structure 120
may rotate counterclockwise on the hinge structure 164a.
[0099] Referring to FIGS. 16 and 17, the first sealing member 781 and the second sealing
member 782 each may be mounted on a curved surface 265b of the second housing structure
120. According to an embodiment, the electronic device (e.g., the electronic device
100 of FIGS. 1 to 3) may further include interfering members 783 disposed at two opposite
edges of the hinge cover 165. The interfering members 783 may extend in the lengthwise
direction (e.g., the y direction of FIG. 3) and may be mounted or attached to the
hinge cover 165. For example, the interfering members 783 may extend substantially
in the y direction of FIG. 3 and be disposed on the hinge cover 165 in parallel with
the first sealing member 781 or second sealing member 782. As shown in FIG. 16, the
interfering members 783 may be interfered with by the first sealing member 781 and
second sealing member 782 in the first position.
[0100] According to an embodiment, the interfering members 783 may include an elastic material
and, when interfered with by the first sealing member 781 or second sealing member
782, they may be compressed while accruing elastic force. For example, at least in
the first position, the interfering members 783 may stably maintain the sealing structure
formed between the outer circumferential surface of the hinge cover 165 and each curved
surface 265a and 265b. As interfering with the interfering members 783, the first
sealing member 781 and the second sealing member 782 may also be compressed, accumulating
elastic force.
[0101] According to an embodiment, in the first position, the first sealing member 781 and
the second sealing member 782 may be in the state of contacting or interfering with
the interfering members 783, as much as a first area. When the first housing structure
and/or second housing structure (e.g., the first housing structure 110 and/or second
housing structure 120 of FIGS. 1 to 3) rotate to unfold, the first sealing member
781 and the second sealing member 782 may be brought in contact or tight contact with
the outer circumferential surface of the hinge cover 165, as much as a second area.
While contacting or tightly contacting the outer circumferential surface of hinge
cover 165, the first sealing member 781 and the second sealing member 782 may add
up less elastic force than when interfering with the interfering members 783. According
to an embodiment, the second area (e.g., the area of contacting, or tightly contacting,
the outer circumferential surface of the hinge cover 165) may be larger than the first
area (e.g., the area of contacting or interfering with the interfering members 783).
For example, even without interference with the interfering members 783, the first
sealing member 781 and the second sealing member 782 may maintain a stable sealing
structure between the outer circumferential surface of the hinge cover 165 and each
curved surface 265a and 265b.
[0102] Referring to FIG. 18, the electronic device (e.g., the electronic device 100 of FIGS.
1 to 3) may include a second sticky layer 883 formed in the first housing structure
110 or second housing structure 120. The second sticky layer 883 may include a gluing
material applied to a curved surface (e.g., the curved surface 265a or 265b of FIG.
4) of the first housing structure 110 or second housing structure 120. According to
an embodiment, the second sticky layer 883, along with the first sticky layer 581,
may allow foreign bodies present or moving in the space surrounded by, at least, the
hinge cover 165 to stick thereto. For example, the second sticky layer 883 may prevent
free movement of, or contamination of the internal components by a foreign body inside
the electronic device 100. According to an embodiment, the second sticky layer 883
may be formed by directly applying a gluing material to the curved surface 265a or
265b or by attaching a gluing material-applied film-type base material.
[0103] Referring to FIG. 19, the electronic device (e.g., the electronic device 100 of FIGS.
1 to 3) may include a third sticky layer 981 formed in the first housing structure
110 or second housing structure 120. The third sticky layer 981 may include a gluing
material applied to a curved surface (e.g., the curved surface 265a or 265b of FIG.
4) of the first housing structure 110 or second housing structure 120. According to
an embodiment, the third sticky layer 981 may be formed on substantially the overall
curved surface 265a or 265b. For example, the first sealing member or second sealing
member (e.g., the first sealing member 181 or second sealing member 182) may be omitted,
and a portion of the third sticky layer 981 may be disposed in at least a portion
of the area to which the first sealing member 181 or second sealing member 182 of
FIG. 4 is attached in the curved surface 265a or 265b. The third sticky layer 981,
along with the first sticky layer 581, may allow foreign bodies present or moving
in the space surrounded by, at least, the hinge cover 165 to stick thereto. For example,
the second sticky layer 883 may prevent free movement of, or contamination of the
internal components by a foreign body inside the electronic device 100. According
to an embodiment, the second sticky layer 883 may be formed by directly applying a
gluing material to the curved surface 265a or 265b or by attaching a gluing material-applied
film-type base material. According to an embodiment, a gap G of about 0.1mm may be
formed between the third sticky layer 981 and the hinge cover 165. For example, the
third sticky layer 981 may allow foreign bodies entering the internal space (e.g.,
the space at least partially surrounded by the hinge cover 165) to stick to it without
direct contact with the outer circumferential surface of the hinge cover 165. According
to an embodiment, when the electronic device 100 deforms between the first position
and the second position, the third sticky layer 981 may move about the hinge cover
165 while facing a portion of the outer circumferential surface of the hinge cover
165.
[0104] FIG. 20 is an exploded perspective view illustrating another example of the structure
in which a first sealing member 1081 or second sealing member 1082 is mounted in a
portable communication device or electronic device (e.g., the electronic device 100
of FIG. 1 or 2) according to an embodiment of the disclosure. FIG. 21 is a plan view
illustrating a structure in which a first sealing member or second sealing member
is provided in a portable communication device or electronic device according to an
embodiment of the disclosure.
[0105] Referring to FIGS. 20 and 21, the first sealing member 1081 or second sealing member
1082 each may be mounted at a respective one of two opposite ends of the hinge cover
165. Here, the "edge (or periphery) of the hinge cover 165" may be interpreted as
including an edge or periphery of one surface or area of the hinge cover 165 facing
the front surface of the electronic device (e.g., the electronic device 100 of FIG.
1), with the housing structures (e.g., the first housing structure 110 and second
housing structure 120 of FIG. 1) unfolded as shown in FIG. 1. As described with reference
to FIG. 22 or 23, a portion of the first sealing member 1081 or a portion of the second
sealing member 1082 may protrude from the outer circumferential surface of the hinge
cover 165. According to an embodiment, the first sealing member 1081 or second sealing
member 1082 may seal off the gaps between the hinge cover 165 and the housing structures
110 and 120 without being substantially positioned between the housing structures
110 and 120 (e.g., the curved surfaces 265a and 265b of FIG. 4) and the hinge cover
165.
[0106] According to an embodiment, the first sealing member 1081 or second sealing member
1082 may be fastened to the hinge cover 165 by attaching, fusion, or welding. According
to an embodiment, the first sealing member 1081 or second sealing member 1082 may
be fastened to the hinge cover 165 via a coupling structure, e.g., a snap-fit structure
or screw. According to an embodiment, the hinge cover 165 may have a slit(s) extending
along its lengthwise direction, and the first sealing member 1081 or second sealing
member 1082 may be fastened, partially inserted into the slit formed in the hinge
cover 165.
[0107] According to an embodiment, the first sealing member 1081 or second sealing member
1082 may be a plate of rigid material, formed of, e.g., a metal, e.g., SUS. According
to an embodiment, when the first housing structure 110 or the second housing structure
120 rotates, the first sealing member 1081 or second sealing member 1082 may slide
and contact the inner surface (e.g., the curved surface 265a or 265b of FIG. 4) of
the first housing structure 110 or second housing structure 120. In the structure
of sliding and contacting the curved surface 265a or 265b, the first sealing member
1081 or second sealing member 1082 may be formed of a synthetic resin, e.g., an acetal
resin with superior mechanical strength and lubricity. According to an embodiment,
the first sealing member 1081 or second sealing member 1082 may include silicone,
sponge, or a fabric surrounding sponge.
[0108] FIGS. 22 and 23 are cross-sectional views illustrating a modified first sealing member
1081 or second sealing member 1082 in a portable communication device or electronic
device (e.g., the electronic device 100 of FIG. 1 or 2) according to various embodiments
of the disclosure.
[0109] Referring to FIGS. 22 and 23, the first housing structure 110 or second housing structure
120 may include a bend(s) 110e or 120e in a portion of its edge, e.g., at the edge
of the curved surface 265a or 265b. According to an embodiment, the bends 110e and
120e may be arranged to be substantially symmetrical with each other and may be aligned
substantially in parallel with the direction of radius of curvature of the curved
surface 265a or 265b or the direction of radius of curvature of the outer circumferential
surface of the hinge cover 165. For example, if the curved surface 265a or 265b or
the outer circumferential surface of the hinge cover 165 extends along the circumferential
direction with respect to the folding axis A (e.g., the folding axis A of FIG. 1),
the end faces of the bends 110e and 120e may be arranged to face the folding axis
A.
[0110] According to an embodiment, in the cross-sectional view of FIG. 22 or 23, the first
sealing member 1081 and second sealing member 1082 are mounted on two opposite top
edges of the hinge cover 165, and a portion of the first sealing member 1081 or second
sealing member 1082 may protrude from the outer circumferential surface of the hinge
cover 165. According to an embodiment, in the state of the first housing structure
110 and the second housing structure 120 being folded to face each other, e.g., in
the first position of FIG. 2, the first sealing member 1081 may be disposed to tightly
contact a first bend 110e of the bends 110e and 120e, and the second sealing member
1082 may be disposed to tightly contact a second bend 120e of the bends 110e and 120e.
According to an embodiment, the sealing members 1081 and 1082 may be disposed to seal
off the gaps between the outer circumferential surface of the hinge cover 165 and
the bends 110e and 120e. For example, in the first position, the first sealing member
1081 may seal off the gap between the end face of the first bend 110e and the outer
circumferential surface of the hinge cover 165, and the second sealing member 1082
may seal off the gap between the end face of the second bend 120e and the outer circumferential
surface of the hinge cover 165. According to an embodiment, a portion of one surface
of the first sealing member 1081 may tightly contact the hinge cover 165, and another
portion of the surface of the first sealing member 1081 may tightly contact the first
housing structure 110, e.g., the first bend 110e. Similar to the first sealing member
1081, a portion of one surface of the second sealing member 1082 may tightly contact
the hinge cover 165, and another portion of the surface of the second sealing member
1082 may tightly contact the second housing structure 120, e.g., the first bend 120e.
According to an embodiment, in the state of the first housing structure 110 and the
second housing structure 120 being unfolded side-by-side, e.g., in the second position
of FIG. 1, the first sealing member 1081 or second sealing member 1082 may contact
the first hinge plate 164b or second hinge plate 164c. For example, in the second
position, the first sealing member 1081 or second sealing member 1082 may seal off
the gap between the hinge plate 164b or 164c and the hinge cover 165.
[0111] As such, the first sealing member 1081 or second sealing member 1082, at least in
the first position or second position, may seal the internal space (e.g., the space
where the folding axis A is positioned) of the hinge cover 165 off the other space.
According to an embodiment, the first sealing member 1081 or second sealing member
1082 may slide and contact the inner surface (e.g., the curved surface 265a or 265b)
of the first housing structure 110 or second housing structure 120. For example, when
the housing structures 110 and 120 rotate on each other, the first sealing member
1081 or the second sealing member 1082 may slidingly contact the curved surface 265a
or 265b, sealing off the gap between the hinge cover 165 and the curved surface 265a
or 265b.
[0112] FIGS. 24 and 25 are cross-sectional views illustrating a modified portable communication
device or electronic device (e.g., the electronic device 100 of FIG. 1 or 2) according
to various embodiments of the disclosure.
[0113] Referring to FIGS. 24 and 25, the electronic device may include dummy members 1181
and 1182 (e.g., the sealing members 1081 and 1082 of FIGS. 20 to 23) provided in the
hinge cover 165. According to an embodiment, the dummy members 1181 and 1182 may be
formed integrally with, or separately from the hinge cover 165 and, if formed separately
from the hinge cover 165, the dummy members 1181 and 1182 may be assembled or attached
to the hinge cover 165. According to an embodiment, the dummy members 1181 and 1182,
albeit being similar to the sealing members (e.g., the sealing members 1081 and 1082
of FIG. 23) in the foregoing embodiments, may not contact the first housing structure
110 or second housing structure 120. For example, in the first position, the dummy
members 1181 and 1182 may be disposed to face the first housing structure 110 or second
housing structure 120 to partially hide the gaps (e.g., first gaps G1) between the
hinge cover 165 and the housing structures 110 and 120 or, with predetermined gaps
(e.g., second gaps G2) left therebetween. As such, some portions of the dummy members
1181 and 1182 in, at least, the first position, may hide the gaps between the hinge
cover 165 and the housing structures 110 and 120, and other portions of the dummy
members 1181 and 1182 may be disposed to face the inner surfaces of the housing structures
110 and 120.
[0114] The first gaps G1 may be formed to be small enough to prevent influx of foreign bodies
from the outside. However, the disclosure is not limited to such a specific embodiment
and, as described above in connection with the foregoing embodiments, the dummy members
1181 and 1182 may seal off the gaps formed between the hinge cover 165 and the housing
structures 110 and 120. The first gap G1 may be the distance between the hinge cover
165 and the first housing structure 110 (or second housing structure 120) which is
measured in the horizontal direction of FIG. 24, and the first gap G1 may be about
0.05mm. However, the first gap G1 between the hinge cover 165 and the housing structure
110 or 120 is not limited to the specific value. For example, the first gap G1 may
be designed with various values considering the rotation of the housing structures
110 and 120 or cutoff of influx of foreign bodies.
[0115] According to an embodiment, the dummy members 1181 and 1182 may be, e.g., metal plates
and may include a first dummy member 1181 mounted on a side edge of the hinge cover
165 and a second dummy member 1182 mounted on its opposite side edge of the hinge
cover 165. According to an embodiment, the first dummy member 1181 and the second
dummy member 1182 may partially protrude to the outside of the hinge cover 165. For
example, when viewed from the outside of the hinge cover 165 in the first position
(e.g., the state as shown in FIG. 5) in which the first housing structure 110 and
the second housing structure 120 are folded to face each other, a portion of the first
dummy member 1181 may be exposed to the outside via the gap, e.g., the first gap G1,
between the hinge cover 165 and the first housing structure 110. According to an embodiment,
when viewed from the outside of the hinge cover 165 in the first position, a portion
of the second dummy member 1182 may be exposed to the outside via the gap between
the hinge cover 165 and the second housing structure 120. For example, the first dummy
member 1181 and the second dummy member 1182 may at least partially hide the gaps
between the hinge cover 165 and the housing structures 110 and 120. According to an
embodiment, the first dummy member 1181 and the second dummy member 1182 may at least
partially block off foreign bodies entering from the outside via the gaps (e.g., the
first gaps G1). In this embodiment, the first dummy member 1181 or second dummy member
1182 is exposed to the outside via the first gap G, but the disclosure is not limited
thereto. For example, when an end of the first bend 110e has a shape including an
inclined surface or curved surface corresponding to the outer circumferential surface
of the hinge cover 165, there may be gaps between the hinge cover 165 and the housing
structures 110 and 120, but the first dummy member 1181 or second dummy member 1182
may be invisible to the outside. According to an embodiment, the first gaps G1 may
be small enough not to be identified with the naked eye and, although there are gaps
between the hinge cover 165 and the housing structures 110 and 120, the first dummy
member 1181 or second dummy member 1182 may be invisible to the outside.
[0116] According to an embodiment, in the first position, a portion of the first dummy member
1181 may be disposed to face the inner surface (e.g., the first bend 110e of FIG.
23) of the first housing structure 110. For example, in the first position, a portion
of the first dummy member 1181 and the inner surface of the first housing structure
110 may be arranged to face each other while leaving a second gap G2 therebetween.
The second gap G2 may be the distance between the first dummy member 1181 and the
first housing structure 110, as measured in the vertical direction of FIG. 24, which
may be about 0.13mm. According to an embodiment, in the first position, the second
dummy member 1182 may be disposed to face the inner surface of the second housing
structure 120 while leaving the second gap G2. The specific values for the second
gap G2 between the first dummy member 1181 and the first housing structure 110 or
between the second dummy member 1182 and the second housing structure 120 are merely
an example, and the disclosure is not limited thereto. For example, the second gap
G2 may be designed with various values considering the rotation of the housing structures
110 and 120 or cutoff of influx of foreign bodies. According to an embodiment, as
described above in connection with the foregoing embodiments, the first dummy member
1181 or second dummy member 1182 may come in contact with the inner surface of the
first housing structure 110 or second housing structure 120, sealing off the gap between
the hinge cover 165 and the housing structure 110 or 120.
[0117] According to an embodiment, the embodiment of the structure including the dummy members
1181 and 1182, in combination with the sealing members (e.g., the third sealing members
481a and 481b) of FIGS. 9 to 12, may be disposed in the electronic device (e.g., the
electronic device 100 of FIG. 1 or 2). Although the dummy members 1181 and 1182 include
metal plates, as an example, in the instant embodiment, the disclosure is not limited
thereto. For example, the dummy members 1181 and 1182 may be formed of an elastic
material, e.g., sponge or rubber, or a synthetic resin film that is rigid but thin
enough to provide flexibility. According to an embodiment, the dummy members 1181
and 1182 may be formed of a composite material of at least two of a metal plate, an
elastic material, and a synthetic resin film.
[0118] FIG. 26 is a cross-sectional view illustrating a modified portable communication
device or electronic device (e.g., the electronic device 100 of FIG. 1 or 2) according
to an embodiment of the disclosure.
[0119] Referring to FIG. 26, in the first position, a third gap G3 may be formed between
the hinge cover 165 and each housing structure 110 and 120. The third gap G3 may be
smaller than the first gap G1 of FIG. 24, and the third gap G3 may be, e.g., about
0.03mm. According to an embodiment, to form the third gap G3 smaller than the first
gap G1, the housing structure 110 or 120 (e.g., the first housing structure 110) may
include a first protrusion 110f, and the hinge cover 165 may include a second protrusion
1281. In the first position, the first protrusion 110f may be positioned adjacent
to the second protrusion 1281, and the third gap G3 may substantially mean the distance
between the first protrusion 110f and the second protrusion 1281.
[0120] According to an embodiment, the first protrusion 110f (or the second protrusion 1281)
may be of the shape of the metal forming the first housing structure 110 (or the hinge
cover 165). According to an embodiment, the first protrusion 110f (or the second protrusion
1281) may be a portion of a painted or coated layer and may be formed on the surface
of the metal forming the first housing structure 110 (or the hinge cover 165). According
to an embodiment, the first protrusion 110f (or the second protrusion 1281) may be
formed by additionally painting or coating a required portion (e.g., the edge of the
outer circumferential surface of the hinge cover 165), on the surface of the metal
forming the first housing structure 110 (or the hinge cover 165). According to an
embodiment, the first protrusion 110f may be formed of a synthetic resin by joining
(e.g., by welding) another metal member to the first housing structure 110 or by insert-molding.
According to an embodiment, when the first housing structure 110 is formed of a synthetic
resin, the first protrusion 110f may be formed of a synthetic resin via dual injection
molding. According to an embodiment, the first protrusion 110f may include a tape
or a member attached to the first housing structure 110 or the second housing structure
120 via a tape. For example, the first protrusion 110f may stick out from the inner
surface of the first housing structure 110, as long as the thickness of the tape and/or
the member attached by a tape. According to an embodiment, the member attached by
a tape may include an injection-molded article or a metal structure.

hinge cover 165. As set forth above, according to an embodiment, the first sealing
member 1381 or the second sealing member 1382 may be integrally formed with the hinge
cover 165. Although FIG. 27 illustrates that the first sealing member 1381 and the
second sealing member 1382 are separate components arranged symmetrically with each
other, the disclosure is not limited thereto. For example, the first sealing member
1381 and the second sealing member 1382 may be integrally formed with each other and
may be attached along the edge of the hinge cover 165. According to an embodiment,
the first sealing member 1381 and the second sealing member 1382 may be shaped to
form a closed curve and may be attached along the edge of the hinge cover 165.
[0123] According to an embodiment, third sealing members 1383a and 1383b may be attached
onto the inner surface of the hinge cover 165, at two opposite ends of the lengthwise
direction Y. According to an embodiment, the third sealing members 1383a and 1383b
may be disposed to form closed curve trajectories with the first sealing member 1381
and the second sealing member 1382. According to an embodiment, when the first sealing
member 1381 and the second sealing member 1382 are integrally formed together or are
shaped to form a closed curve, the third sealing members 1383a and 1383b may at least
partially be disposed in the area surrounded by the first sealing member 1381 and
the second sealing member 1382.
[0124] According to an embodiment, in implementing the real-world product, the above-described
embodiments may be combined together or replaced. For example, the sealing members
181 and 182 disposed in the housing structures 110 and 120 of FIG. 4 may be replaced
with the sealing members 1081 and 1082 of FIG. 20 or the dummy members 1181 and 1182
